Zmysnyi M. Means of reliability analysis of radioelectronic systems with complex majority structures

In the thesis solved scientific-applied task of increase degree of adequacy analytical reliability models of fault-tolerant radioelectronic systems (RES) based on majority structure and formation techniques for solving tasks of reliability analysis and parametric synthesis of RES. An analytical reliability model of fault-tolerant RES with reconfiguration of majority structure core, which takes into account the changing rules of vote, is developed. Proposed model of fault-tolerant RES allows to design of radio electronic systems, which can be used operable units and preserve the principle of majority voting for reducing operable technical systems. Two analytical models of reliability of fault-tolerant RES using three majority structures nested in majority structure are developed. Improved analytical reliability model of serviced fault-tolerant RES based on majority structure with sliding redundant and fixed rule of vote, allows solve tasks multi-variate analysis, due to the different variants of the algorithm using reserve and disaster recovery strategies. In the proposed model takes into account the duration of the process of disaster recovery distributed according to the distribution of Erlang. The models of fault-tolerant RES with majority principle of redundancy can solve tasks of reliability parametric synthesis by finding compromises when choosing parameters of fault-tolerant RES and conduct comparative research of their reliability.
